antenna T at; @071 em a: may} Concern h Be it kri'ownthat I, SAMUEL S.CnN'romm, aciltizen of the United States, residing at Smiths Basin, inthe county of Waslr ington State of New York, have invented certain newand useful Improvements in Vessel Emergency-Brakes; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertainsto make and use the same.

This invention relates to brakes and more particularly to ship brakes.

An object of the invent-ion is to provide means for braking the speed ofa vessel and which may be thrown into operation while the vesselistraveling at high speed. 7

Another object is to provide ine'cl'ianism of this character which willbe highly efiicient and effective in use and which will. be of extremelysimple construction and operation.

Another object is to provide brake mechanism of this character includinghorizontally swinging leaves upon opposite sides of the vessel withmeans for controlling the sv'vinging movement; thereof embracing thesame when in operative position.

Another object is to generally improve and simplify the construction ofbrakes of this character and increase the efficiency thereof.

lVith these and other objects in view my invention will be inc-re fullydescribed and illustrated in the accompanying drawings attached to andforming a part of this ap plication, in which 7 Figure '1 is a planview, showing a portion of a hull of a bo'atto which my improved deviceis applied. Fig. 2 is a similar view with the brake mechanism inoperative position. Fig. 3 is a side elevation, showing the brakemechanism in inoperative position. Fig. i is a vertical sectional viewon the line 4-4 Fig. 1. Fig. 5 is a horizontal cross sectional view onthe line 5-5 Fig. 3. Fig. 6 is a view similar to Fig. 1, showing aslightly modifiedform. Fig. 7 is a side elevation of the modified form.Fig. 8 is a vertical section on the line 8-8 of Fig. 7

Referring more particularly to the drawings in which similar referencecharacters designate corresponding parts throughout,

10 designates a conventional form of hull of a vessel to the oppositesides of which the leaves 11 of my brake mechanism are secured. Theleaves 11 have their inner Specification of Letters 'Ia'tent.

vertical edges hinged upon the vertical pins 12 on theouter faces of thesides of the hull, about midway the length thereof.

When in inoperative position, the leaves 11' engage against the sides ofthe hull and the outer orfree vertical "edges thereof are engagedagainst the shield strips 13, forwardly of thepi'n-s 12 and also securedto the sides of the hull. The shield strips 13 and leaves 11 are ofsubstantially the same length and extend from the upper edge of the hullto within a suitable distance of the lower edge of the hull. The leavesand strips are preferably of such length as to extend downwardly to thecurved lower portion 11 of the hull. Thus it'will be seenthat theleaves, pins and strips are positioned only upon the straight portionsof the hull sides. The-leaves 11 are formed of any suitable material andhave pivoted to their upper outer corners the outer ends of the rackbars 14 which are slidably engaged over the upper edges of thehull andengaged by the pi-nions 15 upon the vertical shafts 16 within the vesseland suitably connected wit-lithe engine. To operate the leaves 11 thepinions' 15 are rotated, thus forcing the rackbarsla outwardly andcompelling the leaves 11 toswing upon the pivot pins 12 until at rightangles with the sides of the hull, a s clearly shown in Figs. 2 and 6.

A cable 17 is secured at one end to the lowerouter corner-of each leaf11 and passes around the horizontal pulley 18 secured to the adjacentside of the hull then around the vertical pulley 19 adjacent the pulley18 and also secured to the sides 'of the hull. The cable is thenextended upwardly over the pulley 20 near the upper edge of the hull andabov the pulley 19, then through the side of the'hull, as shown at 20,after which thecabl'e is secured to the pinion shaft 16 in order thatthe cable may be unwound when the pinion shaft rotates in a direction toallow outward movement of the leaf to which the cable is attached anddrawn inwardly or Wound to move the leaf to in operative position, thuscont-rolling the movement of the leaf and preventing the same fromswinging too rapidly upon its pivot pin. If desired the pinion shafts 16may be connected to a portion of the engine to be operated thereby ormay be provided with separate operating means.

The leaves 11 are braced in their outer positions by means of the bracerods 21 having looped ends 22 and 23, the looped ends 22 being engagedor linked with the eyes 2i upon the sides of the hull 10, a spaceddistance rearwardly of the pins 12, while the eyes 23 are slidablyengaged over the curved bars 25 upon the outer faces of the leaves 11,said bars 25 extending transversely across the leaves and having theiropposite ends secured to the same. It will be seen that when the leaves11 are in their outer or operative positions, the loops 23 of the rods21 are atthe other ends of the bars 25, thus securely bracing theleaves. Then the leaves 11 are in their inoperative positions, however,the loops 23 are near the inner ends of the bars 25. Any number of rods21, eyes 22 and bars 25 may be provided but I have shown each leaf 11 asbraced by three rods 21 and a corresponding number of eyes 22 and barsEach guide strip 13 is preferably of substantially triangular form incross section, the vertical edges of the strip being engaged against theface of the hull and the strip being secured along its forward edge orcorner to said hull. As the opposite edge of the strip is free, the facethereof adjacent the outer vertical edge of the leaf 11 will bearagainst said vertical edge and thus prevent casual movement thereof. Theguide strips 13 also serve to prevent the water from playing against theforward edge of the leaves 11 and forcing the latter outwardly.

The modified form shown in Figs. 6, 7 and 8 includes the leaves 26hinged at their inner vertical edges upon the pivot pin 27 on thestraight portions of the sides of the hull 28 and adapted to be swungupon said pins by means of the rack bars 29 with which the pinions 30mesh, said pinions being mounted on the upper ends of the verticalshafts 31, the same as in the preferred form. The cables 32 have theirother ends connected with the lower outer corners of the leaves 26 andpass around the vertical pulleys 33 and the spaced horizontal pulleys 34and 35 and through the openings 36 in the sides of the hull. In thismodified form, however, the inner ends of the cables 32 carry thecounterbalancing weights 37 to prevent too rapid movement of the leaves26 upon their pins 27. In this modified form, the long curved bars aredispensed with and the eyes 38 are secured to the leaves 26 near theouter vertical edges thereof with gagement around the rear verticaledges of the leaves 26 when the latter are in their closed positions orinoperative positions.

hen it is desired to employ this mechanism for braking the speed ofthe'vessel, the pinion shafts are rotated in the proper di rection tocause the rack bars to move outward and thus free the outer verticaledges of the brake leaves of the guide strips and allow said leaves tomove outwardly or swing upon their pivot pins. It will be apparent thatas the leaves are braced at their operative positions upon oppositesides of the vessel, they will efiectively serve to brake the speed ofthe vessel. It will also be apparent that it is simply necessary torotate the pinions in an opposite direction and draw in the cable toreturn the leaves to their closed or inoperative positions, the guidestrips serving to properly guide the free edges of said leaves andretain the same adjacent the sides of the vessel.

It will be apparent that minor changes in the details of constructionmay be resorted to in the scope of the claim without departing from thespirit of my invention.

What is claimed is:

In a brake mechanism for vessels, the combination of a hull, a leafpivotally mounted on the side of the hull with its axis of rotationdisposed vertically with respect to the hull, means for swinging saidleaf to positions against and at an angle to the hull and means forbracing the leaf when the latter is disposed substantially at rightangles to the hull, said means comprising an arcuate rod disposedtransversely of the leaf and having itsterminals secured thereto, aU-shaped bracket secured to the hull and disposed longitudinally of thelatter, and a brace rod having its terminals'slidably engaged with thearcuate rod and bracket respectively.

In testimony whereof, I affix my signature, in presence of twowitnesses.
